Thank you...

struct dirent *dseek(int offset)
{
        struct dirent *dirp;
        ...
        return (dirp);
}
...
...
        while((dirp = dseek(count++))!=NULL)
...

Although it looks like I could still work on my implementation ;)

% cat chdir_output

regular files = 141965, 70.53 %
directories = 57778, 28.70 %
symbolic links = 1467, 0.73 %
char special = 76, 0.04 %
block special = 0, 0.00 %
FIFOs = 0, 0.00 %
sockets = 2, 0.00 %

TOTAL TIME: 27.398438

% cat ftw4_output

Thanks for your help.
